Y09 series laser dust particle counter is used to measure the size and quantity of the dust particle in per unit volume air of clean environment&comma; and may directly test in the cleanliness level of 10 to 300&comma;000 clean environments&period;

This instrument is designed and manufactured according to the light scattering theory of the dust particles&period;By the light irradiation&comma; dust particles will produce a certain intensity of scattered light&comma; which is in proportion with the size of the corresponding particles&comma; so&comma; detecting the intensity of the scattered light could measure the particles sizes&comma; and the number of pulses just for the number of particles&period;

The instrument uses semiconductor laser as the light source of its scattering system that has advantages of focusing on energy and consistent wavelength&comma; so that it will detect more precise and sensitive&period; This instrument is small in size&comma; light in weight&comma; multifunctional and easy to use&comma; and it is very convenient to test clean environment because of its computer-controlled so that can save&comma; print the sampling result&period; No doubt about it&comma; this is an excellent inspection instrument in the area of microelectronics&comma; pharmacy&comma; biotechnology&comma; medicine and health&comma; precision mechanics&comma; optics and space technology&comma; and also ideal for evaluation of various kinds of clean environment&period;
